[PATCH] CodingStyle cleanup for kernel/sys.c
From: Cal Peake
Date: Thu Sep 14 2006 - 12:11:07 EST
Hi Andrew,
Here's a patch to go with my other one currently in your tree. This one
consistifies kernel/sys.c with CodingStyle. If you think it's too academic
then feel free to ignore :)
- C.
From: Cal Peake <cp@xxxxxxxxxxxxxxxxxxx>
Fix up kernel/sys.c to be consistent with CodingStyle and the rest of the
file.
Signed-off-by: Cal Peake <cp@xxxxxxxxxxxxxxxxxxx>
